Notes

The project.max-shm-memory resource control restricts the total amount of shared memory a
project can allocate. The system-imposed maximum on the size of a shared
memory segment is therefore a function of the sizes of any other
shared memory segments the calling project might have allocated that are still in
use. For accounting purposes, segment sizes are rounded up to the
nearest multiple of the system page size. See getpagesize(3C).

The system-imposed limit on the number of shared memory identifiers is maintained
on a per-project basis using the project.max-shm-ids resource control.
